TAS Z1

Compact total station for rapid topographic and engineering surveys.

Compact total station for rapid topographic and engineering surveys.

Hardware guarantees high-precision results

150MHz modulation frequency, shorter precision measurement ruler, and higher accuracy at the same signal-to-noise ratio and phase discrimination resolution. The new optical path design fully isolates the transmitting and receiving optical signals, ensuring high accuracy

Hardware guarantees high-precision results

Coping with road measurements in complex situations

A brand new road measurement program that can calculate horizontal and vertical curves of any type of road, allowing for discontinuous changes in the radius of horizontal curves, including non-complete transition curves with any large deviation angle, straight line elements with straight turning points, and any broken chain piles

Coping with road measurements in complex situations

Convenient and reliable data processing

Support EXCEL table data and DAT data import and export. Add known point files, all projects can call known point coordinates

Convenient and reliable data processing
